l `Specification form-ing part of Letters Patent No.' 78,869, dated lJune 1d, 1868. 1.'

To 'all z oh'om it may enamelv Beit known that L UEARLEs M. FRENGH, of

4 Rochester, in the coun ty of 4Beaver and State .of'Pennsylvtmia, have invented a new and useful Improvement in Plowsg and I do hereby' declare that the following is a full and exact' on af-line at right angle to the 'longitudinal plane of the vshare-har, said joint, share,='and mold-board. being so arranged' with relationto each other as to give strength and 'depth to the sharebar-*at thepoint where the lille ot' ,the jjoint betweenthe shareandJnoldhcard crosses ffthe'longitndina-l 'plane of the s'harebar,'the

whole being constructed, arranged, and'operlA ating in the'manner hereinafter described. e

To enable'others skilled in thejartV to. make andfuse Illy-invention, [will proceedto de.

" Y to become bent and catchthe iinerootsor other scribe its construction and operation. l

In the accompany-ing drawings, whichform part of my specitcation, Figure lis a perspective view f my' improvement in-plows. 1 Fig. `2is a section ofthe plow, and represents a side o'r'face View of the share-baratti] landside.

In the d rawing s,g/represents themold-board; G, the share 5v X, the standard; h, the cutter; f, "the sharebar; -D ,thelandside; l-2, 3,14, 5,6,

and 7, the bolts' for securingt'he severalparts I together,

' Themoldhoard, share, share-bar, landside,

:struction of myV improvement, what I claimv as'of my-inye'ntio'n isf Socon'structing a. plow 'asi that the joint b eand cutter arel made of east-'s t'el..` E The standard X ismade' of east-iron, and made 'i'nany of the forms used for to theform of the parts whiclrare to. be attached to Vi t..-']2he beam andhandles 'of the plow are constructed of wood and made inan'y` i'ot' the known formS, and are secured-t0 the standard X, mold-board 9 landside D, and".

share-hanf by means of the bolts marked2,

and dotted line o shown in Eig-f2:

tern for the desired landside; The'moidboard is. made'frbm sheets fof cest-steel, which are the co`nstruction`ol'. st eell plo-wsggbut iuevery'case the contour ofthel lower part of thestandard X must correspond cut to theform' and size of the pattern desired for the mold-board, andl byl theuse of a metal former is bent to .the desired curvature.

The share G and its bar f are secured to the standard X by means of the bolt 5, and the' .mold-board gis secured'in its position on the standard X by means of the lbolts marked 1.1 -The landside is secured to the standard X by means of the bolts 4. The lower end ofthe cutter'isitted ina cavity' made in the share",

as shown at the point'- mar'ked n, and the 'upper end is secured to the standard X bytneans of the bolts'.I 1

By making the joint A between the share C .and inoldf'hoard g .straight and `ona line' at right angle to the longitudinalv plaaieofthe landside depth and strengthwillbe given to thesharebar' f att-he pi")int B V and the shelli- 4der will heformed for theilntdifthe lajti!" side D, to rest against,and the sharp point (indicated by th e,dottedlinesaround letter B inJFg. 2) 'will be avoided: This sharp point', when'A made. part et the landside, is'very liable ber in the ground* l By making the joint A in the, manner del `scribed .the joint can be planedlin a planingmachine and lfitted. perfectly true, and by the general construction'pf the plow theV several "parts can 'bev'easi'l y and with 'great facil-ity duplicatedwheu desired. 2

I wish .it-'clearlyl understood `that I'do not claim: liroadl y la' straight joint between the' plowsh-areand mold-board;v but, j j

Having thus described the nat-ure and contween the share and mold-'board shall'be about on aline at' right vangle tn the plane of the shareba-r or 'landsidefof the"plow, said' joint being so arranged with relation to the share and'moldLboard as-'to give depth .and strength tothe forward-partici the share-bar, and also sojthat theseveral parts may be duplicated',

vthe.'A whole .beingv constructed, arranged, and operating substantially as herein described, "and for .the purpose set forth-.
